To reduce the consumption of unprocurable and expensive charcoal or eliminate it from the silicon production process, alternative reducing agents and a silicon smelting technique for reduction furnaces operation are much needed. This article considers the possibility of using a new-generation solid carboncontaining reducing agent, rexil, obtained from non-caking Shubarkol long-flame coal, for the electrothermal production of metal silicon. Using rexil reduces the amount of charcoal in the charge and can also expand the raw material base, as well as preserve the country’s forested areas.

使用新一代含碳还原剂电热生产硅 – Rexil

为了减少无法采购和昂贵的木炭的消耗或从硅生产过程中消除它，非常需要替代还原剂和用于还原炉操作的硅熔炼技术。本文考虑了使用新一代固体含碳还原剂 rexil 的可能性，这种还原剂是从不结块的 Shubarkol 长焰煤中获得的，用于电热生产金属硅。使用 rexil 可以减少炉料中的木炭数量，还可以扩大原材料基地，以及保护该国的森林地区。
